The 31-year-old joined Prince William and Prince Harry in the Swiss Alps yesterday for the wedding of polo player Mark Tomlinson and Laura Bechtolsheimer, Olympic gold medalist in dressage. Technically, Harry escorted Kate to the ceremony at Arosa ski restort, because Will was busy acting as an usher (hence, the pink tie). Fortunately, the duchess seemed to be enjoying herself, sharing a laugh with Harry and throwing confetti into the air as the newlyweds passed by.

So what did the mom-to-be wear to celebrate the society nuptials? It looks like Kate wore the same printed MaxMara Studio dress from her visit to Cambridge in November, the brown Lock & Company pillbox hat she wore during St. Patrick’s Day festivities last year, Emmy shoes, an Annoushka pearl necklace and an Emmy clutch. We don’t seem to remember seeing that cream coat or fur stole before, so perhaps they’re a couple of her recent purchases — she has been shopping quite a bit, after all.

In case you haven’t quite gotten to marking your calendars, Catherine is just about five months pregnant and due to give birth in July. Back in December, the Duchess of Cambridge was hospitalized for acute morning sickness, but she’s seemed to get back on schedule after the new year. Hey, even those with a royal bun in the oven have obligations…
